近年来,福建海洋工程装备产业进步显著,初步形成了以港口装卸、海上起重机、海底铺管、大型汽车滚装船等传统装备为主导的制造基地;同时,海水淡化核心装备、海洋防腐材料、水下作业机器人、游艇装备等新兴产业也取得了快速发展,但仍存在产业基础薄弱、整体产品低端、研发力量小且分散、试验研发平台严重不足等制约"瓶颈"。文章通过现场调研和资料查询分析了福建海洋工程装备产业的发展现状,总结归纳出当前制约产业发展的主要因素,明确发展思路,提出建设具有海西特色的海工装备制造业应发展海洋工程装备的重点领域、编制福建省海洋工程装备中长期发展规划和实施方案、提升海洋工程装备科技创新能力、制定海洋工程装备发展的扶持政策、构建比较完整的重点领域海洋工程装备产业链等对策与建议。 相似文献

Sorption and desorption behavior of residual antidepressants and caffeine in freshwater sediment and sewage sludge 总被引：1，自引：0，他引：1

The use of antidepressants is widespread in modern times. Thus, they present a potential risk for ecosystems due to occurrence in domestic sewage containing unaltered metabolites and structures, even after the treatment plants have processed the sewage. The current research investigated the sorption and desorption of antidepressants(citalopram, venlafaxine, fluoxetine, sertraline, and amitriptyline) and caffeine from freshwater sediment and sewage sludge. The samples of freshwater sediment were ... 相似文献

战略性新兴产业的迅速发展,无论对中国还是对世界经济都具有全局带动和重大引领作用,而稀土当之无愧地成为战略性新兴产业的重要支柱性矿产之一。随着中国稀土产业的不断发展壮大以及政策宏观调控的作用,加之终端消费产业的需求拉动稀土消费,我国的稀土需求一直呈增长态势,而新兴领域的应用的不断开拓,使稀土资源需求结构也发生的很大变化,本文通过分析近年来稀土资源需求变化,为下一步稀土资源管理提出相关政策建议。 相似文献

90年代发展中国家国际资本流入的新特点及其影响 总被引：1，自引：1，他引：0
从1992年起,流向发展中国家的证券资本以较大的优势超过了国际直接投资。在全球经济一体化、金融市场自由化和国际化的背景下,国际资本跨国流动呈现出规模巨大化、运作方式机构化、流动形式多样化的特点。庞大证券资本的注入在给新兴市场国家带来益处的同时,也可能造成伤害,这一点在墨西哥和东南亚金融危机中已经得到证实。因此防范和化解国际资本的流入所带来的金融风险,是新兴市场国家当前所面临的严峻课题。 相似文献

This paper examines knowledge production networks in the fund management industry. Focusing on Asian emerging markets (EMs), I explore how fund managers, brokers and research analysts utilise a combination of texts, analytical structures, codified procedures, and social networks to generate interpretations and perspectives on Asian EMs. Utilising a process-based approach, I investigate how ‘EMs’ as an investment category is imagined and practiced by those in the fund management industry through knowledge networks and how such networks are produced and maintained. Discussions are drawn from interviews conducted with 22 EMs specialists in Singapore and London. I argue that Asian EMs have distinct characteristics that are acted upon and reproduced by finance workers in particular ways and that the acquisition and transfer of tacit knowledge takes on increased significance when codified knowledge structures are lacking. Actors in Singapore and London are also embedded in different knowledge networks, which offer different strategic advantages but, when taken together, form a complex and multi-layered knowledge production network of ‘imagineering’ Asian EMs from both within and outside of Asia. 相似文献

AbstractIn this commentary, we highlight some of the strengths of the bibliometric analysis conducted by Qin et al. that examines the relationships between environmental and natural resource sociologies through citation networks, coauthorship, and keyword usage. We also suggest some ways that the analysis could be expanded or built upon, and ideas for further distinct, but related, inquiry. We also reflect on our own identification, training, and mentoring within the two subfields and draw upon responses from a small purposefully selected sample of other early/mid-career environmental and natural resource sociologists to start a conversation about what the relationship between the two fields might look like in the future. 相似文献

The specific geographic location and natural conditions of the Arctic region play a significant role in the global climate change. As a result of perennial low temperature, simple ecological structure, and fragile ecosystem and weak stability in the Arctic, Persistent Organic Pollutants (POPs) accumulating from the region of middle and low latitudes may cause tremendous pressure in the arctic ecological environment. Therefore, the research of POPs in the Arctic region is not only conducive to more in-depth understanding of POPs distribution and transformation process in the global range, but to reasonably assess the harm of human activities on the arctic ecological environment. Thus, in the past 40 years, especially after nine new kinds of emerging organic contaminants being added to the list of Stockholm Convention in 2009, more and more scientific community and general public have pay attention to the research of POPs in the Arctic region. At present, the understanding of legacy POPs in the Arctic is limited, and the research of emerging POPs is in the initial stage. This paper aimed to summarize some conclusions and implications of the research, and focused on the occurrence level, historical evolution, bioaccumulation and source of POPs in atmosphere, waters, sediments and organisms in the Arctic region. Finally, the future changes and key scientific problems of POPs in the Arctic region were proposed. 相似文献

SARS (Severe Acute Respiratory Syndrome) has been declared by WHO (World Health Organisation) as a global health threat. Within
a period of four to five months in 2003, the disease infected some 8,000 people in more than 25 countries and left 774 dead.
The many studies that have been done on the spread of SARS in Asia as well as countries as far flung as Germany and Canada
have focused on the global dimension of the infectious disease as well as the speed of its spread upon emergence in southern
China and then Hong Kong. Less attention has been paid to its spatial distribution at the national and local scales. This
discussion focuses on the spread of SARS at the national and local spatial scales. In the process, the study presents the
management of a hazard, in this case, an emerging infectious disease by national health care institutions such as the hospitals
that ultimately proved to have been wholly unprepared for coping with at least the health aspects of the outcome of a globalised
national agenda for growth and economic progress. 相似文献
